Laminating equipment is generally divided into two categories, namely pre-coating laminating machine and coating laminating machine; pre-coating laminating machine due to some objective constraints.
        As a result, it is rarely used in China and has not been popularized, but the development prospect is very good; that is, the coating laminator is widely used and has stable performance, and is currently widely used; large and small batches of lamination processing. At present, there are advanced automatic machines in China, which have promoted the price difference of laminating machines.
        That is, the film coating equipment is a special equipment that applies the adhesive to the reel plastic film after being dried, and then pressurized composite parts are combined with the printed matter. It is divided into two types: automatic laminating machine and semi-automatic laminating machine. The working principle of each model is the same. The structure and the laminating film are unique. They are roughly divided into unwinding, gluing, drying, laminating, It consists of five parts for rewinding and auxiliary devices such as automatic tension control, mechanical transmission, and automatic deviation adjustment for unwinding.

        Machines such as pre-coated film equipment are special equipment for compounding printed materials with pre-coated plastics. Its biggest feature is that there is no sizing and drying part, and it has fewer steps than the instant film coating equipment; so this type of machine has a compact structure, low cost, easy operation, and high stability. The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-pressing zone compounding, and automatic rewinding. And other auxiliary devices.
